Abstract: A system and method for providing reputational information on users involved in transactions is detailed. The method includes evaluating fulfilment of transactions, particularly in the context of contracts, and providing a record of that on a blockchain through reputational information, which can be retrieved later. Similar reputational information for other transactions can be retrieved and linked to the same user, based on a hash of a master public key for a user. Aggregate reputational information can be computed from pieces of reputational information retrieved. The evaluation and record provision can be implemented using a deterministic finite automaton (DFA). For each user involved in each contract, the DFA not only configures and allows for implementation of the contract, but also considers the extent of fulfilment of the contract's terms. The DFA generates reputational information in relation to each user in each contract, and this reputational information is published to and stored on the blockchain.

Abstract: Techniques enable creation of a preview license for digital content. In some instances, the preview license indicates that it allows a content-consuming device to consume less than all of the content. This preview license may create a list specifying multiple portions of the digital content that the content-consuming device may consume. These techniques may also present to a device user an offer to purchase rights to consume all of the digital content after consumption of the preview-licensed portion(s). In other instances, a content server may embed the preview license into a content package that contains the digital content, allowing the server to distribute the package to multiple devices. In still other instances, the preview license may be bound to a domain rather than to individual devices. This allows member devices to share the digital content and the preview license, such that each member device may enjoy the preview experience.
